P0110 Code: Intake Air Temperature Sensor 1 Circuit (Bank 1)The “sensor 1” portion of the code applies to vehicles that have multiple IAT sensors. Bank 1 points to the side of the engine opposite the #1 cylinder.
Code P0110 is triggered when the PCM perceives that the signal from the intake air temperature (IAT) sensor circuit does not match P0113 Code: Intake Air Temperature Sensor 1 Circuit High InputWhen the PCM gets a signal voltage reading above the maximum value, it realizes that the IAT sensor circuit has malfunctioned, either because the sensor is unplugged, the terminals are damaged, one of the sensor wires has been cut, or some other open circuit issue.
